I had this problem with a pair of magnepan 3.3's and I fixed it myself. The wires that are bonded to the mylar panel come loose as they loop at the top and bottom of the speaker. If you look through the cloth at the back of the speaker (use a flashlight) you can see this. Magnepan sells a jar of blue speaker panel coating. You have to peel the sock off the speaker to repair it. I decided to slit the sides of the sock at the top and bottom and spray glued it back on after making the repair . This was easier than taking the whole thing apart. After you gain access to the wires, use 3m spray glue to bond the wires back onto the mylar. Then coat that area with the blue magnepan coating. I laid the speaker face down on the dining room table to do this as you only need to access the back of the speaker. I did this 2 years ago and the speakers still sound fantastic. I think they sound better than when they were new!!
Magnepan 3.5R buzzing
I have a 2 year old pair of Maggie 3.5R's and recently when playing some music which contains low bass the one speaker's top mid-bass panel plays the music but there is a buzzing along with the music. Has anyone had this problem, is there a quick fix thatI can perform w/o having to send back to Magnepan?
